Avalanche Model — self-organized criticality explains market crashes

Avalanche Model — self-organized criticality explains market crashes
50k ft — Why care?
Markets reach self-organized criticality where small perturbations trigger cascading failures. The 'news' doesn't cause the crash — the system was already at a critical state. Applies sandpile/avalanche dynamics from physics to explain market fragility.
10k ft — Key takeaways
• Crashes aren't caused by news — system was already critical
• Self-organized criticality: small triggers → large cascades
• Monitor criticality metrics, not news headlines

Stop looking for the "news" that caused the crash. 📉
Traders look for the "news" that caused the drop. Quants know the truth: The market was already broken; the news just tipped it over.
This is the Bak–Tang–Wiesenfeld model. The crash is a feature, not a bug.

In physics, there’s a concept called Self-Organized Criticality. Imagine dropping grains of sand one by one. For a long time, nothing happens. The pile just grows.
But eventually, the system reaches a "Critical State." The pile becomes so unstable that a single grain—indistinguishable from the millions before it—triggers a massive avalanche.
